| 4.1.7 | The difference between bandwidth and broadcast domains
A bandwidth domain is everything associated with one port on a bridge or switch. In the case of an Ethernet switch, a bandwidth domain is also known as a collision domain. All workstations within one bandwidth domain compete for the same LAN bandwidth resource. All the traffic from any host in the bandwidth domain is visible to all the other hosts. In the case of an Ethernet collision domain, two stations can transmit at the same time, causing a collision.
